To all whom it may concern.'

Be it known that we, Onur R. SiiinNsoN 'and OLAF M. SnrnNsoN, citizens of the have invented a new and usetul Pole-ltd Versing Switch and Vvviiinke- System, ot' which the following isy a specification.

Tt' is the object of t'iis invention to proL Vide a. pole reversine' switch, the terminals4 ot' which are eonnee ed in a novel and -iinproved inanner to provide tor the reversing of the eiirrent.

Another ohjeet of the invention is to provide a ,ri'itatal'ile ineinlier, of novel and iinproved torni, adapted to engage the termi nals, and to provide novel means t'or h-old ingl the rotatable memlier lioth in engagement with the terminals and out ot engagement with the same.

Another ohjeet ot' the invention is to improve generally the eonstruetion oli pole re- Versing` switehes, so as to enhanee their.

strength, and wearing' qualities,y and to laeilitate their operation.

lVith the foregoing1 and other ohjeeta in view which will appeal' as the des-eliption proeeeds, the invention residesl in the eoinhination and arrangement ot parts and in i the details oF eonstruetion hereina'l'ter deserilied and elaimed, it heini;` understood that ehanges in the preeise embodiment ot invention herein diselosed ean he madel withvin the scope oli what is elaiined without departing trom the spirit ot the invention.

ln the drawinlgsf-Figure l is a liottom plan; Fig. 2 is a transverse seet'ion on they line fe-l of Fig'. l: Fie'. S is a transverse section on the line, (lfd) ot Fig. l: lt`ig. -flis a top plan oi" the hase of the switeli. the top heine' removed, vand parts heineT omitted: Fig. 5 is a top plan ot tho switeh. showing the top assemhled with the. hase, the

View depiet'ing the swil'eh as it will appear when in use; and Fig. ,t is a seelion detail of the top of the deviee.

ln carrying out the invention` there is provided a hase lv` ordinarily eireular in outline and fashioned trom insulating' material. 'lhis hase l is provided with an upstandmg peripheratflange l (see, Figs; 2 and il) to whieh Aa top L) is threaded` as Shown at it. ln the. hase At there are. several eouiiter-'sunk` holes` fl, adapted to i'eeeivo/serews or the like, wheieliy the. hase. l may he eoniieeted with ay su pport.

The hase l. is provided with. a principal terminal 5. a primary terminal tl. an intermediate terminal lt). an au\iliar ir terminal S. a seeondar)v terminal T, and an intermediate terminal 9. disposed in the order named. around the renter of the hase l, and upstanding' slightly tlieieahove. These teiniinals are exteudetl downwardly through the hase l. and are held in position by' nutandl washer ronneet'ions ll. located. in reeesses liy .iiithe lower taee ot the base l. wire or"`other eonduetor ll unites the principal ,tern'iinal with the auxiliary ter- /niinal QQ A wirt or other conductor l5 unites the primary terminal' G with the seeondaiv terminal 7. These eonduetors lltl and '1.3 are seated in 4moves 1G `formed in the upper tare otj the hase l. the `grooves 1G, atter the eonduetors are seated therein, heine' tilted with paratliii or the like. i

'there an openingA in the topI 2. sur rounded h v a hearing` eollar 17 in which a stem lh is mounted for rotation. To the upper end ol the .stem l?? i thuinh pieee 19" is .seemed hy means ot a set' serew '20. Projeetiim' i'adiall)Y trom the stem 'ttl and l0- eated heneath the top 2 are projeeting pins 21 and 21. loeated .ltl" apart. Spring pawls 2'2 are erin-ed to the inne'l tare ot' the top 2. M their t'i'ee ends. these. spring pawls hear upon `oppositel)v disposed pins` so as to limitI the rotation ol'Y the stem lil. 'lhere are seats "23 in the pawlsA 2Q adj-arent their ends and these seats engage the pins 2l and 2l to hold the Adem ll in predetermined positions. Referring* to Fig. tt it will vhe noted that. although the stein tti/may lie rotated in one direetion. the stem can-notitie rotated in an opposite direetionl since the tree ends oli the pawls 39. `being helow the pins when not.` resting' thereon` will prevent sueh reverse rotation.

llie lower end ot the stem 18 is iournaled l'or rotation in the hase l. and extends through the hase l into a reeess lin the lower `t'aee olf the hase. nut and washer eonueetion 25. loeated in the reeess 2l, serves to hold the stein iR in plaee. The stein 18 is squared as shown at QG, to eno-age a disk QT. so that. the disk and the stein will rotate together. 'lhe dish' 27 is ordinarily faslb ioned lfi-'om hard rnhher` although any other suitahle. insulating material may he used. A washer 2S rests upon the. upper "taee, `of the disk Q7 and surrounds the stem t8. [t pin 2t) or the like, is inserted through the stern 18, to hold the washer 28 and the dislr 27 in place against upward movement.

ln the Opposite edges of the disk 7 therel hield in place in the grooves 30 by means of ma screws or other securingdevices suitable for the purpose.v Upon the outer face of the top 2, as shown in Fig. 5, marks 36 may be made to indicate when the circuit is open throughethe switch, and when the circuit is closed. i

lThe device as above described may be employed under all conditions where a pole changing switch is called for. lt will be found useful in the spark mechanism of`internal combustion engines.

Referring particularly to Fig. t wherein is shown the switch of the present invention located in an electric circuit, a battery l0 appears. From the positive pole of the battery LG a conductor l39 extends to the principal terminal 5, it being clearly disceri'iible in Figs. 2 and 3 that all of the terminals are adapted at their lower ends for connection. with conductors. F rom the intermediate terminal 9 a conductor 37 extends, this conductor 37 being connected to the intermediate terminal. 10. lt will of course be understood that in this conductor 37, any desired electrical apparatus may be positioned.v F rom the primary terminal G a conductor le extends to the negative pole of the battery 40, the battery 40 being shown conventionally, to indicate any suitable source of electrical energy..

In noting Figs. 2 and 4, it will be seen that when the arm 31 of one bridge rests upon the principal terminal 5, the other arm of the same' bridge, denoted by the numeral 32, rests upon the intermediate terminal 9. When this bridge piece is positioned as above described, the arm 33 of the other bridge piece-will rest upon the primary terminal4 6, the arm 3ft of the last named bridge piece resting upon the terminal 10. At this point it may be stated that the resit ent material, so that proper contacts may brice pieces are preferably fashioned from 'e obtained. `ien the bridge pieces are positioned as shown in It, the spring pawls 22 rest upon the pins 21 and hold the several arms of the bridges in place upon the terminals upon which they bear. Moreover, 'owing to the construction seen in Fig. G, the rotatable member embracing the stem 18, the disk 27 and the bridges can be rotated in but one direction only, that is, in the direction of the. arrow B in Fig. 4f. Supposing, therefore, that the rotatable member were turned in the direction of' the arrow E through an arc of 180, it will be seen that the arm 34 will rest upon the intermediate terminal 9, the arm 33 resting upon the sccondary terminal 7, the arm 31` resting upon `the auxiliary terminal 3, and the arm 32 40, the current will pass through the con-i.

ductor 39 to the principal terminal 5, through the arms 31 and 32 to lthe intermediate terminal 9, through the conductor 37 to the intermediate terminal 10, thence through the arms 34 and .33 through the primary terminal 6, and thence through `the conductor 414 to the battery 40. In case, however, the rotatable member has been moved through an arc of 180, as hereinbefore pointed out, the current, coming from the battery 410 will pass to the conductor 39 to the principal terminal 5, through the yconductor 14 through the Aauxiliary terminal 8, through the arms 31 and 32 to the intermediate terminal 10 through the conductor 37 to the intermediate terminal 9, through the arms 34 and 33 to the secondary terminal 7,

through the conductor 15 to the primary terminal 6, and through the conductor 4A to thc battery 40. Therefore, when the parts of the device are positioned as shown in 'Fig 1, the current, following the arrows A will pass through the conductor 37 in one direction, while if the rotatable member be turned about through 180O as above set forth, the current'will pass throughl the conductor 37 in a direction contrary to the arrows A; the function of the pole changing switch being thus consununated.

It is to be noted that when the seats 23 at the ends of the spring pawls 22 are engaged with the pins 21 in thc stem 18, the circuit through the switch will be open, and in such instance, the button 19 will be positioned with respqctto the marks 36, as shown in Fig. 5, thus indicating that the circuit is open through the switch.
